A bag dispensing apparatus and a bag dispensing system are disclosed. The bag dispensing apparatus includes a housing, a bag retaining mechanism, and a bag locking mechanism. A roll of bags is stored in the bag dispensing apparatus and a leading bag of the roll of bags can be directly hanged on the bag dispensing apparatus for use. The storage and use of the bags are cleverly integrated to save the space, and the operation is more convenient.

One embodiment relates to a bistable hold open mechanism including first and second flexible flat, strip like members positioned relative to each other, The members include opposing first and second ends; an inner mating surface; and an opposing outer bonding surface, One or more pivot members and/or hinges is integrated into the second member separating it into a side seal portion and an operable portion, the side seal portion coupled to the operable portion. Embodiments include flexures which allow the pivot members or hinges to be biased in open or closed configurations. Appling a slight pressure to the members opens the mechanism. When the mechanism reaches a predetermined point, the pivot or hinges lock, maintaining an open configuration. Closing the mechanism only requires a slight pressure be applied to the external surface of the members, resulting in the pivot members or hinges unlocking and rotating towards a closed configuration.

A packaging sheet is described. The sheet comprises a first rigid component, a second rigid component, and a multilayer film. Each of the first rigid component and the second rigid component comprises styrenic polymer, aromatic polyester, aliphatic polyester, polypropylene homopolymer, or blends thereof. The multilayer film is a blown, coextruded film positioned between the first rigid component and the second rigid component and comprises (a) an outer layer, (b) a barrier component, and (c) an inner layer, where the barrier component is positioned between the outer layer and the inner layer. The first rigid component is coated on or laminated to a first surface of the multilayer film and the second rigid component is coated on or laminated to an opposing second surface of the multilayer film such that the sheet is not a fully coextruded sheet. Various embodiments of the sheet are also described.

A surface bonding fastener includes first and second members that can be fastened with each other. Each of the first and second members includes a base sheet and a plurality of fastening units on and integrally molded with the base sheet. Each of the fastening units has first and second hooks. The first hook has a first body and a first hook portion. The second hook has a second body and a second hook portion. The first and second bodies are adjacent to each other in a transverse direction and integrally formed on the base sheet. The first and second hook portions are respectively extend from the first and second bodies and bended toward opposite directions. An overlapping degree between the first and second bodies in a longitudinal direction is configured to be determined by a desired fastening strength between the first and second members.

A packing bag to store a stored article Z with tight seal by a welded sheet material 1 of resin in which a separation-prepared line portion 5, separable by predetermined tensile force F by human hands to take out the stored article Z, is provided along an opening-prepared side portion 10, the sheet material 1 has a layered unit construction in which first and second welding resin layers 61A and 61B are disposed on both sides, and a barrier layer is disposed on a middle position, the separation-prepared line portion 5 is composed of a half-cut first laser-worked groove 7A concaved on the first welding resin layer 61A and a half-cut second laser-worked groove 7B concaved on the second welding resin layer 61B, and, the first and second laser-worked grooves 7A and 7B are formed barely damaging the barrier layer 60.

A securable clip includes a first elongated rectangular portion and a second elongated rectangular portion connected along a common edge. The clip includes at least one locking peg, at least one receiving hole configured to receive the at least one locking peg, and a frangible portion. The frangible portion provides a visual indication that the clip has been opened. The releasing of the locking peg prevents the clip from being reclosed, reused, or sealed again.

A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.
